Abstract

The invention provides a method of making a component from first and second parts which are joined in a welding process wherein a laser beam is transmitted in a direction from a laser source and at least partly into a gap. The gap is made between edges of the component, and to enable a faster laser welding process, the laser has a focus point size which is at least of the size of the gap. To enable better control of the width of the gap, the invention further provides a method and components wherein one part is formed with a neck which extends into a complementary socket of the other part to prepare the parts for the welding process. The invention in particular concerns welding of brass.
